摘要
文章以某型受电弓为例,分析受电弓在几种可能的异常工况下的失效情形,并结合弓网事故案例和异常工况时受电弓的失效形式,建议受电弓应设计相应的薄弱结构。当出现异常工况时,受电弓薄弱结构首先遭受破坏,使受电弓脱离接触网,从而保护接触网。
Taking one pantograph as an example, this paper analyzes the failure modes of pantograph under several possible abnormal conditions. Referring to the pantograph-catenary accident cases and failure modes of pantograph under abnormal conditions, it suggests that the pantograph should be designed with corresponding weak structures. When abnormal conditions occurring, the weak structure of pantograph is destroyed first, and the pantograph can disengage itself from catenary easily, so that the catenary can be protected.
